Software License for The QuaDRiGa Channel Model
© Copyright 2011 - 2019 Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.
All rights reserved.
1. INTRODUCTION
The Quadriga Channel Model ("QuaDRiGa") is used for generating realistic radio channel impulse
responses for system-level simulations of mobile radio networks. These simulations are used to
determine the performance of new technologies in order to provide an objective indicator for the
standardization process in bodies like the third generation partnership program 3GPP.
Quadriga was developed at Fraunhofer HHI to enable the modeling of MIMO radio channels for specific
network configurations, such as indoor, satellite or heterogeneous configurations. Besides being a
fully-fledged three dimensional geometry-based stochastic channel model, QuaDRiGa contains a
collection of features created in SCM(e) and WINNER channel models along with novel modeling
approaches which provide features to enable quasi-deterministic multi-link tracking of users
(receiver) movements in changing environments.
